Certainly Apple's payment method needs to be scrutinized closely, but I think it may be a little more secure than what you're describing here:
=When you add your credit card via the camera or typing it in, the information is encrypted and transmitted to Apple and then your bank. Your bank screens you to make sure you're you then generates a Device Account Number and some keys for creating transaction ID's. Then Apple deletes your credit card info (except for a portion to use to ID you if you call for support) from their servers and your phone.
The photo isn't stored and your credit card info isn't stored on your phone or at Apple.
= Since the Device Account Number (generated by your bank) is the only info used during transactions, your bank can easily deactivate payments on your device without having to go through the time and expense of deactivating your card.
Find My iPhone doesn't have to talk to your phone to deactive payments, it simply tells your bank to deactivate the Device Account Number. Meanwhile your credit card still works. So whether your phone is near WiFi or even on has no bearing on deactivating payments from your device.
